Detailed Description
The terms "first," "second," and "third," etc. in the description and claims of the present invention and the above-described drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprises" and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.
Referring to fig. 1 and fig. 2, fig. 1 is a flowchart of a document printing control method according to an embodiment of the present invention, and fig. 2 is a simplified flowchart of the document printing control method according to an embodiment of the present invention. By the file printing control method, the file to be printed or the initial file of the file to be printed is processed, so that a printer file is generated and sent to the printing equipment to control the printing equipment to print. The file printing control method can be operated on electronic equipment, and the electronic equipment comprises a computer, a personal computer, a notebook computer, a tablet computer, a network server, a mobile phone, a personal digital assistant, an intelligent wearable device, a printing auxiliary device connected between a client and the printing device and the like. The printing apparatus may include, but is not limited to: a copying machine, a printer, a facsimile machine, or a multifunction peripheral (MFP) that integrates the functions of the copying machine, the printer, the facsimile machine into a single system, and the like.
Specifically, the file printing control method includes the following steps S11-S15.
In step S11, a document to be printed is acquired. Specifically, the step S11 may be executed in an electronic device, and in an embodiment, an application program of the electronic device acquires an initial file and converts the initial file into the file to be printed in a preset format, so that the application program (e.g., a print driver) of the electronic device may acquire the file to be printed in the preset format. Therefore, the step S11 may include: acquiring an initial file; and converting the initial file into the file to be printed in a preset format.
The initial file may have different formats, such as WORD, EXCEL, PPT, PDF (Portable Document Format), and the like, and the preset Format of the file to be printed includes PDF but is not limited to PDF. Of course, it is understood that, in some embodiments, some applications (such as the office software WPS) of the electronic device may also directly generate the file to be printed in the preset format, and correspondingly, in step S11, an application (such as the print driver, but not limited thereto) of the electronic device may directly receive and acquire the file to be printed in the preset format without performing format conversion.
In addition, in some embodiments, the electronic device may also receive a file to be printed sent by an external device or a network server, or receive an initial file (e.g., an initial file in a format such as WORD) sent by an external device (e.g., an external other electronic device) or a network server, and convert the initial file into a preset format (e.g., through WPS office software) to obtain the file to be printed in the preset format (e.g., the file to be printed in a PDF format). In addition, in some embodiments, the electronic device may also generate the initial file, the initial file is provided to an external device or a network server and converted into the file to be printed in a preset format (for example, the file to be printed in the PDF format), and the file to be printed in the preset format is returned to the electronic device, so that the electronic device obtains the file to be printed.
Step S12, identifying an image object in the file to be printed. The file to be printed may include image objects, text objects, and the like, and specifically, in step S12, the image objects in the file to be printed may be identified by analyzing the file to be printed. Further, when the file to be printed is in a PDF format, the image objects in the file to be printed may be identified by an internal PDF identification analysis module or by calling another application program capable of implementing PDF identification analysis, and the PDF identification analysis module or PDF identification analysis application program may identify all the image objects in the file to be printed.
Step S13, determining whether the image object has a preset attribute. The preset attribute may be a mask, that is, in step S13, it is determined whether the image object of the document to be printed is an image object with a mask, and it is understood that the image object with a mask generally includes a main image and a mask. The mask may have different transparencies ranging from 0% to 100% and may be disposed on the main image to shield the main image to different degrees. As shown in fig. 3(a), fig. 3(a) is a schematic diagram of a to-be-printed file including an image object with preset attributes, where the to-be-printed file may include an image object and a text object, and first, through step S12, the whole to-be-printed file is analyzed to identify the image object of the to-be-printed file, as shown in fig. 3(B), fig. 3(B) is a schematic diagram of the image object of the to-be-printed file; further through the step S13, it is determined whether the image object has the preset attribute, specifically, as shown in fig. 3(B), it may be determined by querying to know a mask type in the picture details of the image object, and if the mask type in the picture details is an external mask, it is determined that the image object has the preset attribute of the mask, and then step S14 may be further performed.
Step S14, if the image object has the preset attribute, performing optimization processing on at least the image object portion of the file to be printed to obtain a processed print file.
In one embodiment, in step S14, the whole of the file to be printed may be optimized to obtain the processed printed file. In another embodiment, in step S14, the image object portion of the file to be printed may be optimized, and the processed image object is used to replace the original image object to obtain the processed printed file.
Specifically, in step S14, the optimizing process may include at least one of removing transparency and reducing compression rate, that is, the step of performing the optimizing process on at least the image object portion of the document to be printed may include: at least one of removing transparency of at least the image object portion of the document to be printed and reducing compression rate of at least the image object portion of the document to be printed. The transparency removal is used for enhancing the image quality and improving the printing speed; the reduced compression ratio is used to save decompression time. Further, the optimization process may further include a step of performing image preprocessing optimization of at least the image object portion before performing at least one of the steps of removing transparency and reducing compression rate.
Further, when the step of removing the transparency is performed, it may be determined whether the image object portion has only the bottom layer image or has no covering relationship, and if the determination result is yes, the step of removing the transparency may be performed to remove the transparency of the image object portion. That is, the step of performing optimization processing on at least the image object portion of the document to be printed may include: and judging whether the image object part only has the bottom layer image or has no covering relation, and if so, executing a step of removing the transparency of at least the image object part of the file to be printed.
Further, the step of removing the transparency of at least the image object portion of the document to be printed may specifically include at least one of the following three ways (for example, using one of them, using any two of them in an overlapping manner, or using all three in an overlapping manner):
(1) removing transparency from at least the image object portion by calling a file format conversion module (e.g., GhostScript);
(2) removing transparency from at least the image object portion by a PDF processing module;
(3) performing screenshot processing on at least the image object part to obtain a screenshot image, and covering at least the image object part with the screenshot image so as to remove transparency of at least the image object part;
still further, in the above manner (3), before the step of removing the transparency of at least the image object portion of the document to be printed, the following determination step may be further performed: judging whether a file format conversion module (such as GhostScript) or a PDF processing module can be called to remove the transparency of at least the image object part, if the judgment result is negative, then executing the step of the mode (3): and performing screenshot processing on at least the image object part to obtain a screenshot image, and covering at least the image object part with the screenshot image so as to remove the transparency of at least the image object part. It is understood that, among others, the file format conversion module GhostScript is a file format conversion module that is self-contained by an operating system of a general electronic device. The format of the processed print file includes, but is not limited to, the PostScript format with extension PS.
Step S15, converting the processed print file into a first print file. The first print file is to be sent to a printing device to control the printing device to print. It will be appreciated that the first printed document may have a language in which the printing device is able to directly receive and execute a print job in dependence on the first printed document, i.e. the first printed document may be recognized and directly printed by the printing device. Specifically, the extension of the first print file may be a PRN, but is not limited to the above.
And step S16, sending the first print file to a printing device to control the printing device to print. Further, it is understood that, in the file printing control method, the determination result in step S13 may be: the image object does not have a preset attribute, e.g., the image object does not have a mask, and thus, the file printing control method may further include steps S17 and S18.
Step S17, if the image object does not have the preset attribute, converting the file to be printed into a second print file. The second print file is used for being sent to the printing device to control the printing device to print. It will be appreciated that the second print file may have a language in which the printing device can directly receive and execute a print job in dependence on the second print file, i.e. the second print file may be recognised by the printing device and printed directly. Specifically, the second print file may be in the same format as the first print file, such as with an extension PRN, but is not limited to the format described above.
And step S18, sending the second print file to a printing device to control the printing device to print. The step S18 may also be executed by a print driver of the electronic device, but is not limited thereto. It can be understood that the first print file and the second print file may both be sent to the same printing device, and of course, may also be sent to different printing devices, and may be set by the user according to the requirements of the user.
It should be understood that, the steps S11-S18 may be executed by the print driver of the electronic device, but not limited thereto, and may also be executed by an application program such as an office of the electronic device, the print driver, and/or other internal and external applications, which are not exhaustive.
As can be seen from the above, in the file printing control method according to the embodiment of the present invention, the first print file or the second print file is finally generated and sent to the printing device by acquiring and processing the file to be printed or the initial file of the file to be printed, so as to control the printing device to print, thereby completing the control of file printing.
However, the embodiment of the present invention also provides a processing method of a file to be printed, which may include some steps (such as steps S11-S14, or steps S11-S15, or steps S11-15 and S17) in the file printing control method of the above embodiment, so that the file to be printed or an initial file of the file to be printed is processed to generate the processed print file, or the first print file, or the second print file. By the method for processing the file to be printed, the processed print file, the first print file or the second print file can be generated, wherein the processed print file can be further provided to other electronic equipment or a network server to be further converted into the first print file; the first printed file can also be sent to other electronic equipment or a network server, and the like, and according to actual needs, the other electronic equipment or the network server can send the first printed file to printing equipment so as to control the printing equipment to print; the second print file can be sent to other electronic devices or a network server, and the other electronic devices or the network server can send the first print file to a printing device according to actual needs so as to control the printing device to print. It can be understood that the first print file and the second print file may both be sent to the same printing device, and of course, may also be sent to different printing devices, and may be set by the user according to the requirements of the user.
The file processing method to be printed in the embodiment of the present invention can also be operated on electronic devices, where the electronic devices include, but are not limited to, computers, personal computers, notebook computers, tablet computers, network servers, mobile phones, personal digital assistants, intelligent wearable devices, printing auxiliary devices connected between clients and printing devices, and the like. The printing apparatus may include: a copying machine, a printer, a facsimile machine, or a multifunction peripheral (MFP) that integrates the functions of the copying machine, the printer, the facsimile machine into a single system, and the like.
